Application filed April 14, 1921.

To aZZ whom it may concern:

Be it known that 1, PETER A. Prizes, on, a citizen of the United States, reslding at Pueblo, in the county of Pueblo and State of Colorado, have invented certain new and Q useful Improvements in A .hl.'l-R0ll8l' luxtures; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to shad rollers and more particularly to the fixtures cooperating therewith, whereby the shade may be raised or lowered and made secure in the required adjusted position by proper manipulation of a cord.

The invention obviates the usual spring roller and the objectionable features incident thereto, such as the tugging at the shade when it is required to effect a winding thereof or to hold the same in the desired adjusted position, the frequent rapid winding of the shade when released which causes the stick in the lower end of the shade to wedge between the roller and the window frame, or the failure of the shade to wind when fully unwound from the roller.

The present invention insures an even winding of the shade on the roller, prevents tearing of the shade and insures a steady winding or unwinding thereof accordingly as the operating cord is manipulated and enables the shade to be instantly'released for unwinding and instantly fastened when adjusted to the required position.

Other objects and advantages will be apparent and suggest themselves as the nature of the invention is understood.

While the drawings illustrate an embodiment of the invention it is to be understood that in' adapting the same to meet different conditions and requirements, various changes in the form, proportion and minor details of construction may be resorted to without departing from thenature of the invention.

Referring to the acompanying drawings forming a part of the specification,

Figure 1 is a front view of'the upper portion of a window provided with a shade roller embodying the invention, v

the roller showing the manner of attaching the shade thereto.

Corresponding and like parts are referred to in the following description and desig nated in the several views of the drawings by like reference characters.

The numeral 1 designates a window frame, the same being shown to demonstrate the application of th invention. The shade roller is supported at one end by means of a bracket 2 which receives the pin or ournal thereof. The opposite end of the shade roller is supported by a fixture which constitutes the subject matter of the present invention. The shade 3-is secured to the roller 4 by means of a strlp 5 and a groove 6. The groove 6 extends substantialy the entire length of the roller 4 and is provided in a side thereof. An edge portion of the shade 3 is pressed into the groove 6 by means of the strip 5, the latter being made secure by means of brads or in any preferred way. The outer side of the strip 5 is flush with the roller 4 to insure a smooth winding of the shade on the roller.

The fixture embodies a bracket 7 which-is secured at one end to the window frame 1 in any preferred way. The outer end of the bracket 7 has pairs of lugs 8 on its top side which are spaced apart to receive between them a hanger 9. Projections 10, at opposite sides of the hangar 9, enter the spaces formed between the lugs of the respective pairs. This arrangement holds the hanger 9'in predetermined position and admits of the same having the limited movement laterally and longitudinally necessary to the free operation of the shade in the manner later set forth. The casing or frame of the fixture is supported by means of the hanger 9.

The casing or frame is preferably of seetional formation and comprises relatively front and rear sections 11 and 12, respectively. The lower portion of each of the sections 11 and 12 is cut away to form a space or opening 13 when the sections are properly assembled. The sections 11 and Y12 are formed with relatively upper and lower, ears Hand 15, respectively, said earsbeing transversely apertured to receive bolts or like fastenings whereby the sections are made secure when broughttogether. The upper cars 14 are received between the depending elements of the hanger 9 and are held thereto by a bolt or fastening 16.. The lower ears 15 are connected by bolts 17 or like fastening means. I

FAIspool: is rotatably mounted'in the casing or frame and comprisesa spindle 18and circularrims or heads 19.

the casing orframe and the meeting pop tionsare annularly grooved to form races to receive balls '20 which provide anti-friction bearings and locking means to hold the 20 spoolin proper position; A socket 21 is provided at the inner end of the spool and receives the adjacent end of the shade roller 4 which is secured therein in any manner.

frame'and cooperate'with "a pawl 23 to hold 1 the shade 3 atthe required adjusted position. v'ljhepawl 23 preferably forms part of a frame pivotally connected to the casing and comprising a curved arm 24:, a straight arm 25.:anda tie r6d'26. "The arms 2tand 25 are spaced "apa'rt 'a distance to receive a cas ing between them and their ifree ends "are connected by the tie rod 26. The curved arm'24clearsthe socket 2l 'and the ratchet teeth-22 thereon." The'upper ends of the arms 24 'and'25 arepivotally connected to ears 2'7 projecting from the rearfsection 12 of the'casi ng'. The ratchet teeth 22 face in a die Erection to preventacloc'kwise movement of the-spool when engaged bythe pawl 23. This .prevents'unwinding of the shade 3 and holds ;the same inthe required adjusted position. 'The' pawl 23 is adapted to ride on the ratchet teeth 22 when winding the shade 3 upon the roller l. Anoperating cord 28is made fast at one .end"to:the spool andpasses beneath the tie rod 265 The operating cord 28', after having one'end thereofpassed' through an opening 28. in the-'spindIe lSand then knotted to prevent- =its withdrawal, is fwound upon the :spool'in a reverse direction to the winding of the shade 3 on the "roller 4. NVhen the shade3 is fully wound upon the roller 4, the operating cord 28 is practically unwound :-f:1"om.the spool with the possible exception of'one oritwo winds. Ifjit be required to :lower the s'hadeythe lower portion of the .c'ord.:28 'isgra'sped and drawn outward away from the wlndow whereby'it is brought into contact-with thetie rod 26 and swings the lower end .of the pawl frame outwardly whereby. to disengage the awl 23ffromthe teeth -'22,;and upon manipu ating the cord to The rims or 15 heads 19 fit snugly within end portions of ment of the "spool from permit an upward movement thereof, the

shade lowers by unwinding from the roller 4 due to the weight of the stick or bar 29inswings inwardly and brings thepawl 23 into engagement with one of the ratchet teeth 22, whereby the shadeis held in the adjusted position. To raise the shade 3, it is'neces;

sary only to pull upon the cord 28, whereby it is unwound from the spool and effects a rotation of the roller 4L to wind the shade'3 thereon. Duringthis operation, the pawl 23 rides on. the ratchet teeth 22 and upon releasingthe cord 28, the shade is'instantly' held in the adjusted position'beoause of'the engagement of the 'pawl123 with a ratchet I toothed 22. :Ratchet teeth 22 are disposed at the inner -end'of the socket :21 adjacent the casing What is claimed is: 1. A shade roller lixturec'oinprising a longitudinally separable" casing, a" spool mounted within the casing, with 'the ends of jthespool constituting end closures for the casing, theopposing portions: of the ends of the spool and the'casing being anriularly grooved, and balls in the matching grooves forming means to prevent displacethe casing and antifriction bearings. i 5

2. A shade roller fixture comprising a casing including relatively front and rear sections having theirlower portions cu y intermediate the ends to for'm'a space'when the sections are assembled, fastening means, said sections having outwardly extehding apertured ears coacting with said fastening means whereby the 'sections are made secure, a spool mounted within theca sing, with the ends of the spool constituting end closures for'the'casing," the endsof the spool and casing beln'g an'nularly' grooved and balls in the matching grooves forming means to prevent displacement of the spool from the casing and'anti frictionbearings.
